Chemical additive for improving the water flow rate of the membrane {CHEMICAL ADDITIVES FOR ENHANCEMENT OF WATER FLUX OF A MEMBRANE} |
| abstract |
An interfacial polymerization process is provided for producing highly permeable thin film composite membranes used for nanofiltration, forward osmosis or reverse osmosis, especially for use in brackish water at low energy conditions. The process was coated by contacting a porous support membrane with an aqueous phase containing a flow-enhancing combination of a polyamine and a bidentate ligand and a metal chelate additive containing a metal atom or metal ion and an additive comprising phosphoramide. A step of forming a support film, and a step of applying an organic phase containing a polyfunctional acid halide to the coated support film and interfacially polymerizing the polyamine and the polyfunctional acid halide to form a distinction layer of the thin film composite film including. A membrane produced by the method and a reverse osmosis module containing the membrane are also provided. |
